Import PLL Frequency Launches Incorrect Parameter Editor

Environment

  • Quartus® II Subscription Edition
  • PLL
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    If you click Import PLL Frequency, the ALTLVDS_TX parameter editor correctly starts, but you can incorrectly edit all parameters not just the Frequency /PLL Settings page parameters.

    This issue affects all configurations.

    There is no design impact.

    Resolution

    To work around this issue, when the ALTLVDS_TX parameter editor starts on the General parameters page, follow these steps:

    1. Click Next to go to the Frequency/PLL Settings page.
    2. Select desired input clock rate.
    3. Click Finish twice to skip the remaining pages and close the ALTLVDS_TX parameter editor.

    This issue will be fixed in a future version of the POS-PHY Level 4 MegaCore function.
